In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei.

Researchers have made the first experimental determination of the weak charge of the proton. The results also include the determinations of the weak charge of the neutron, and of the up quark and ...

This proton-coupled electron transfer (PCET), as it is known, does not produce any change in charge -- the most efficient way for a redox reaction to occur.

Proton’s mass radius is apparently shorter than its charge radius The quarks that give it charge aren't hanging out with the gluons that provide mass.

Discovery of protons Throughout most of the 19th century, it was thought that atoms were the smallest and most basic building block of all matter, but as that century neared its end, the evidence ...

A research team led by Prof. Pan Feng from the School of Advanced Materials, Peking University Shenzhen Graduate School has ...

Key Concepts Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the ...

An international team of researchers at the US Department of Energy's Jefferson Accelerator Laboratory in Virginia has measured the weak charge of the proton for the first time. Although first ...

Scientists make the most precise measurement yet of the proton’s weak charge and find it agrees with predictions.

Researchers have made the first experimental determination of the weak charge of the proton in research carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility.
